WAVE-MOTOR.

To all whom it may concern Be it known that I, GERHART HEOKERMAN, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Wave- Motors, of which the following is a specification.

My invention relates to a motor to be used for producing power caused by the motion of the water along the shores of theoocean or sea, preferably in the breakers, and the objects of my invention are: first, to provide a wave operated-motor of this class which utilizes the force of the waves in their inward and outward movement as well as in their upward and downward movement; second, to provide a wavemotor of this class in which the power of the waves is directed for raising weights which are allowed to ravitate downwardly producing power;

third, to provide'a wave motor of this class in which the pendulum or float in the water produces power which is connected sepa-' rately throughdifferent transmission mechanism for revolving a shaft in one direction at all times; fourth, to provide a mechanism of this class in which the clutch mechanism is operated and controlled automaticall by the movement of the pendulum or oat; fifth, to provide a mechanism of this class in which a plurality ofunits may be connected together for revolving a shaft in one direction at all times; sixth, to provide a mechanism of this class 'whichis adjustable throughout andvery flexible and seventh,

to provide a mechanism ofthis class which is simple and economical of construction, durable, easy to operate,easy to install and which will not readily deteriorate or get out of order.

With these and other objects'in view aswill appear hereinafter my inventlon consists of certain novel features of construction,combination and arrangement of parts I and portions as will be hereinafter described in detail and particularly set forth in the apv pended claims reference being had to the accompanying drawings and to the 'characters of reference thereon which form-a part ofthis specification, in which:

Figure 1 is a perspectlveview of one unit of-my wave motor, Fig. 2 is a side eleva- 7 tional view of the transmission gears of my motor, and Fig. 3 is a partlal elevatlonal -view of theclutch and cable'operating mech- Specificati on of Letters Patent.

anism showing a portion in section to facihtate the illustration.

Similar characters of reference refer to slmllar parts and portions throughout the several views of the drawings.

The float 1, float support 2, cable 3, ad-

justing screws 4, frame 5, levers 6 and 7 shaft 8, drums 9, 10, 11 and 12,.gear .13, pinion 14, gear 15, pinion I6, sheave 17, sheave l8, fly-Wheel l9, cables 20 and 21,

supports 22, bar 23, levers 24 and 25 and weights 26 and 27 constitute the principal parts of my wave motor.

The frame 5consists'preferably of, a rectangularly shaped frame mounted on piles driven at a suitable place in the water near the shore. Pivotally connected to this frame 5 is the one end of the float support 2 on the lower end of which is mounted a float 1 which is adapted to float in the water and move therewith. Secured to this support 2 on one side is the one end of the cable 3 and secured to the other side of the support 2 is the other end of the cable 3 which extends up over pulleys mounted on the frame, then over pulleys 6 and 7 secured on the lower ends of the levers 6 and 7. These levers 6 and 7 are pivoted intermediate their ends-and their upper ends are 7 provided with lugs which engage grooves 9 and 10 in the outer rims of the drums 9 and 10. These drums are revolubly mounted on the shaft 8 which is secured in the supports 8 The other rims of the drums 9 and 10 are provided with ratchet teeth 9 and 10 on their outer surfaces which are adapted to engage with ratchet teeth 11 and 12 on the drums 11 and 12. Revolubly mounted on this shaft 8 between the inner ends of the drums 11 and 12 is the gear wheel 13 which is provided on one side with ratchet teeth 13 secured thereto and on the other side with ratchet teeth 13 secured thereto and secured on the flanges on the inner ends of the drums l1 and 12 are ratchet spring pawls 11 and 12 which are sheave 17 adapted for belt 15 which extends over the sheave 18 andthis sheave l8 secured on the shaft19 and "on this same shaft is secured the fiy-Wheel l9. I H

The cable 8 is wound around the drums 9 and 10 several turns and the loop end extends over pulleys 5 which are pivoted to the frame so as to move to the proper posi-.

tion with the Winding of the cable 3 on the drums 9 and 10. Secured to the drums 11 and 12 are the cables 20 and 21 and they are adapted to wind onsaid drums with the revolution of said drums. The upper ends of these cables are secured to the levers 2 1 and 25 which levers are pivotally mounted on the bar and this bar is supported by ineansof the suppont 22. Mounted on the free ends of'the levers 2 1 and 25 are-the weights 26 and27 which areiadapted to be raised with the winding of the cables 20 and 21 on thedrums 11 and 12 and when released sa-id weights will gravitate, unwinding the cables 20 and 21 and turning the drum and when said drum revolves the spring pawl thereon engages the ratchet teeth secured on the gear 13 revolving said "gear whichin turn turns the fly-whe'el' 19 through the gears 14, 15, 16 and sheaves l7 and 18 and belt 15".

It will be noted that the levers 6 and 7 are connected by a rod 6 so that said levers move simultaneously with the movement of the support 2.

Though I have shown and described a particular construction, combination and arrangement'of parts and portions I do not wish to be limited to this particular cons'truction, combination and arrangement but 'desire'to include in the purview of m invention theconstruction, combination and arrangement substantially set forth in the appended claims.

[It is obvious that with this construction there is provi'deda wavemotor in which the 1 drums are revolved by the movement of the float support and are also shifted longitudi- "nally on theshaft into engagement on one 'side'and' disengagement on the other side so that the movement'of the float automatic a'lly engages and releases the drums upon which the'cables are wound for raising the weights and b'y which the weight revolves the released drum, that while one weight is being raised the other in lowering turns the fly-wheel and main drive shaft so that the mo'vement-offthe plunger raises the weights and the weights by gravity revolve the flywheel.

Having thus described my invention what Iiclaim as, new and desire to secure byfLetters Patent is: r
